The code example (in POD of File::Slurp 9999.19 -> DESCRIPTION -> read_file)
my $bin = read_file( 'filename' { binmode => ':raw' } ) ;
is lacking a comma. It should be:
my $bin = read_file( 'filename', { binmode => ':raw' } ) ;
The exact line (876) addressed can be found here:
https://metacpan.org/source/URI/File-Slurp-9999.19/lib/File/Slurp.pm#L876
It should be corrected, because this causes an error if written like
this and this causes developers additional time, while development.
Searching the error caused by that is not necessary.
